$widget->get_arg("height"); - can we make this work?

I'm not sure why, but it appears get_arg doesnt work - can somebody prove me wrong :) in theory, the widget object has alot of other fields x,y,width,height etc. that could be exported. eg. $widget->height - could be defined in defs.. - I was attempting to do a clist which shows database entries, and fetches only enough to fill the clist, but since I cant work out how big the clist is, i cant calculate how many rows to get... regards alan
